got boost?

[Andrew W. Schlueter]

i dont know if it is this cold weather here in ohio, but i am having
hesitasion in boost. I am running chipped car with the 2.5 pt. ok here is
the issue. 3k rpm, full throttle, nice real fast spool up to 20psi. not any
more. now it goes to 14psi, hesitates then jumps to 20psi. somtimes when i
am full throttle in 4th or 5th it will be at 20psi, it will quickyly drop to
14ish psi then right back up in a matter of a few secconds. you can feel the
loss of power. I am thinking of the N75?? 
 
thanks,
